Companies know that the public falls for marketing ploys. People are always looking for the easy way out and think if they pay more for something it will work better. They forgot however about us
folks that are part of the primitive archer mentality that like to make their own stuff or trade for it. You can make a very effective spine tester for next to nothing.

Google "James Hill Spine Tester"!   I got the dial indicator for mine for $5 at Grizzly Tool Co.

wow, thanks.

this may be elementary but how do i figure what spine weight i need for my or any bow. is it directly related to the pull weight of the bow? say my bow is 50# at 28", do i need my arrows to be 50# spine

Basically yes. There are a few different ways to achieve the right arrow for a 50#@28" bow but the spine tester will put you in the ballpark or closer. The James Hill site has a conversion table showing the relation between the deflection of the shaft and the spine of the arrow.

another question, my bow is 50# @ 28" but my actually draw is closer to 31" to 32" should i be looking for higher splined arrows?
